The mill with a drive power of 370 kW will grind 35 t/h of coal to a product fineness of 15 % R 90 µm. At the same time, the coal, which may have a feed moisture of up to 10 %, is dried in the mill. At the same time, the coal, which may have a feed moisture of up to 10 %, is dried in the mill.

Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.

List of Chinese inventions . China has been the source of many innovations, scientific discoveries and inventions. This includes the Four Great Inventions papermaking, the compass, gunpowder, and printing (both woodblock and movable type).
